Master Lock sells padlocks, which allow you to set your own combination. To reset or change the combinations on the Master Lock, you must know the current combination, whether it is the factory preset combination or a combination that was set after purchase. You will not be able to reset the lock without the current combination. Master Lock sells four models of padlocks model numbers 175, 176, 177 and 178. These instructions work for all four of these models.
